  1. In spite of the trees:plants & woodland management Andrew ByfieldLandscape Conservation Manager

  2. Aimed to measure changes in woodland soils, trees/shrubs & ground flora over 30 year period Resurveyed 103 woodland sites across Britain in ‘2001’ (previously surveyed in 1971) Kirby et al. (2005) Long term ecological change in British woodland (1971-2001)

  3. Overall species richness declined markedly – 36% in plots, 12% in sites ‘Woodland specialists’ more likely than other species to show decreases Stress-tolerant species scores declined and were negatively associated with changes in open habitats. Kirby et al. (2005):Results

  4. Open habitats declined overall Increases in tree basal area were associated with species richness declines other disturbance variables (1987 storm damage, grazing, open habitats) were associated with increased richness Deer / climate change / diff. pollution key Kirby et al. (2005):Results

  5. VASCULAR PLANTS:RARE & THREATENED

  6. 53 rare vascular plants:by microhabitat

  7. Decreasing Montane -8 Calcareous grass -6 Acid grass -3 Broadl. woodland -2 Heath -2 Increasing Improved grass +25 Coast +9 Arable +7 Aquatic +1 Wetland/ Neutral grassl. 0 Declines in common species(BSBI Local change 1987 – 2004)

  8. ‘Common’ coppice species(total 22 species)

  9. Extensive contiguous forests Land uses on various scales Range of timber forest products used Intermittent grazing widespread Diverseactivities widespread Vectors of dispersion present ‘Rare’ species not rare Turkish woodland elements

  10. Habitats not single species focus Fuelwood demands – 50,000 ha – just 15% of total of ancient woodland / PAWS in England Thoughts – part 1

  11. “ We support mechanisms like – but not exclusively – woodfuel that drive an increase in sustainable management of native woodland ..... with strong controls in place to ensure exploitation is sustainable ” Thoughts –part 2
